One False Note

One False Note, a 174 page book by Gordon Korman is about how Amy and Dan continue their journey to find the 39 clues. The music that they found lead them to Mozart's home town and into a dark cave. In the cave, all of the lights go out and boulders fall and block their path! Will they be able to escape and find the 39 clues? Find out by reading this awesome book and its sequels. I would reccomend this book to everyone (who has read the first book.)
